    Abstract: A sensor may include a deformable sensing element having a deformable conductor arranged to deform in response to deformation of the sensing element, wherein the deformation of the sensing element is selectively controlled. The sensing element may be selectively controlled by a restraining element. The restraining element may control the deformation of the sensing element by distributing forces applied to the sensing element. The sensing element may include a deformable body with the deformable conductor arranged to respond to elongation of the deformable body. The deformable conductor may include a conductive gel. A sensor may include a deformable body, a deformable conductor arranged to deform in response to deformation of the deformable body, and a restraining element arranged to selectively control the deformation of the deformable body.

    Abstract: A deformable assembly may include a first structural layer, a first bonding layer bonded to the structural layer, and a pattern of functional material entrapped between the first structural layer and first the bonding layer. The functional material has a viscous characteristic, an elastic characteristic and/or a viscoelastic characteristic. The assembly may further include a second structural layer bonded to the first bonding layer. The first structural layer may include a first piece of fabric, the second structural layer may include a second piece of fabric, and the functional material may be electrically conductive. The functional material may include a conductive gel. The assembly may further include a second bonding layer bonded to the first bonding layer and the first structural layer, and the pattern of functional material may be entrapped between the first and second bonding layers.

    Abstract: A sensor may include a bladder, and a deformable conductor disposed on the bladder such that deformation of the bladder causes deformation of the deformable conductor, wherein the bladder is constrained so as to enhance the deformation of the conductor in response to the deformation of the bladder. A method may include applying a stimulus to a bladder having a deformable conductor attached thereto, detecting a change in an electrical characteristic associated with the deformable conductor in response to the stimulus, and selectively constraining the bladder to amplify the change in electrical characteristic in response to the stimulus.

    Abstract: A flexible differential strain sensor, system, and method includes a deformable substrate having a first axis and a second axis different than the first axis and a first sensing element and a second sensing element. The first and second sensing elements are comprised of conductive gel. The first sensing element is arranged to sense strain in the deformable substrate along the first axis. The second sensing element has a first portion arranged to sense strain in the deformable substrate along the first axis and a second portion arranged to sense strain in the deformable substrate along the second axis. The second sensing element is arranged to cancel at least a portion of the stimulus sensed by the first sensing element in the along the first axis.
